Fire-Fighting Measures Extinguishing media Suitable extinguishing media: dry powder, foam Unsuitable extinguishing media for safety reasons: carbon dioxide Additional information: Avoid whirling up the material/product because of the danger of dust explosion. Special hazards arising from the substance or mixture Hazards during fire-fighting: harmful vapours Evolution of fumes/fog. The substances/groups of substances mentioned can be released in case of fire. Advice for fire-fighters Protective equipment for fire-fighting: Firefighters should be equipped with self-contained breathing apparatus and turn-out gear. Further information: Dusty conditions may ignite explosively in the presence of an ignition source causing flash fire. Impact Sensitivity: Assessment: no 6. Accidental release measures Further accidental release measures: Avoid dispersal of dust in the air (i.e., clearing dust surfaces with compressed air). Avoid the formation and build-up of dust - danger of dust explosion. Dust in sufficient concentration can result in an explosive mixture in air. Handle to minimize dusting and eliminate open flame and other sources of ignition. Personal precautions, protective equipment and emergency procedures Avoid dust formation. Use personal protective clothing. Environmental precautions Contain contaminated water/firefighting water. Do not discharge into drains/surface waters/groundwater. Methods and material for containment and cleaning up Nonsparking tools should be used.

4 Revision date : 2015/09/18 Page: 4/10 7. Handling and Storage Precautions for safe handling Breathing must be protected when large quantities are decanted without local exhaust ventilation. Protection against fire and explosion: Avoid dust formation. Dust in sufficient concentration can result in an explosive mixture in air. Handle to minimize dusting and eliminate open flame and other sources of ignition. Routine housekeeping should be instituted to ensure that dusts do not accumulate on surfaces. Dry powders can build static electricity charges when subjected to the friction of transfer and mixing operations. Provide adequate precautions, such as electrical grounding and bonding, or inert atmospheres. Refer to NFPA 654, Standard for the Prevention of Fire and Dust Explosions from the Manufacturing, Processing, and Handling of Combustible Particulate Solids (2013 Edition) for safe handling. Dust explosion class: Dust explosion class 1 (Kst-value >0 up to 200 bar m s-1). Dust explosion class 1 (Kst-value >0 up to 200 bar m s-1). Conditions for safe storage, including any incompatibilities No applicable information available. Further information on storage conditions: Keep container tightly closed and dry; store in a cool place. 8. Exposure Controls/Personal Protection No occupational exposure limits known. Advice on system design: It is recommended that all dust control equipment such as local exhaust ventilation and material transport systems involved in handling of this product contain explosion relief vents or an explosion suppression system or an oxygen deficient environment. Ensure that dust-handling systems (such as exhaust ducts, dust collectors, vessels, and processing equipment) are designed in a manner to prevent the escape of dust into the work area (i.e., there is no leakage from the equipment). Use only appropriately classified electrical equipment and powered industrial trucks. Personal protective equipment Respiratory protection: Breathing protection if breathable aerosols/dust are formed. Wear respiratory protection if ventilation is inadequate. Wear a NIOSH-certified (or equivalent) organic vapour/particulate respirator. Hand protection: Wear chemical resistant protective gloves. Eye protection: Safety glasses with side-shields. Body protection: Body protection must be chosen based on level of activity and exposure. General safety and hygiene measures: Wear protective clothing as necessary to minimize contact. Handle in accordance with good industrial hygiene and safety practice. Handle in accordance with good industrial hygiene and safety practice.
